Another Stop Loss Issue

[ShruggedAtlas]

I want a stop loss at DonchianChannel upper or lower depending on if I'm long or short. I have drawn a dot on the chart at the appropriate stop placement however applying DoncianChannel indicator parameter to the SetStopLoss function yields a different stop placement than expected. Currently I'm getting a number far below what it should be. it should be 12920 but i'm getting 10348 according to the order tab in the Performance window. what am I doing wrong??

        protected override void Initialize()
        {
            CalculateOnBarClose = true;

        }


        protected override void OnBarUpdate()
        {
			if(CurrentBar <= BarsRequired)
				return;
			
			if(Low[0] > SMA(High, 10)[0] &&
				Low[1] > SMA(High, 10)[1] &&
				Momentum(28)[0] > SMA(Momentum(28), 28)[0] &&
				Position.MarketPosition == MarketPosition.Flat)
			{
				EnterLongLimit(SMA(High, 10)[0], "LE");
				//DrawDot("LD", true, 0, SMA(High, 10)[0], Color.Green);
				SetStopLoss(DonchianChannel(20).Lower[0]);
				DrawDot("TEST", true, 0, DonchianChannel(20).Lower[0], Color.Blue);
			}
			
			if(High[0] < SMA(Low, 8)[0] &&
				High[1] < SMA(Low, 8)[1] &&
				Momentum(28)[0] < SMA(Momentum(28), 28)[0] &&
				Position.MarketPosition == MarketPosition.Flat)
			{
				EnterShortLimit(SMA(Low, 8)[0], "SE");
				//DrawDot("LD", true, 0, SMA(Low, 8)[0], Color.Red);
				SetStopLoss(DonchianChannel(20).Upper[0]);
				DrawDot("TEST", true, 0, DonchianChannel(20).Upper[0], Color.Blue);
			}

		}

Hello ShruggedAtlas,
Thanks for writing in and I am happy to assist you.

Please use the overload SetStopLoss(CalculationMode mode, double value) to set the stop and set the CalculationMode to Price.

SetStopLoss(CalculationMode.Price, this.DonchianChannel(20)[0]);

Please let me know if I can assist you any further.
